Carbohydrates
Carbohydrates are the organic compounds that are obtained in foods and living matters in the shape of sugars, cellulose, and starch. The general formula of carbohydrates is Cn(H2O)2. The ratio of H and O present in carbohydrates is identical to water.
Starch
Starch is a polysaccharide carbohydrate that belongs to the category of polysaccharide carbohydrates.
Mutarotation
The rotation of a particular structure of the chiral compound because of the epimerization is called mutarotation. It is the repercussion of the ring chain tautomerism. In terms of glucose, this can be defined as the modification in the equilibrium of the α- and β- glucose anomers upon its dissolution in the solvent water. This process is usually seen in the chemistry of carbohydrates.
L Sugar
A chemical compound that is represented with a molecular formula C6H12O6 is called L-(-) sugar. At the carbon’s 5th position, the hydroxyl group is placed to the compound’s left and therefore the sugar is represented as L(-)-sugar. It is capable of rotating the polarized light’s plane in the direction anticlockwise. L isomers are one of the 2 isomers formed by the configurational stereochemistry of the carbohydrates.
Label attached stereogenic center as R or S.
The molecule is chiral if the carbon center is attached to four different groups and has non-superimposable mirror images. The word non-superimposable means placing one molecule on top of the other molecule will not give the same molecule. In the given molecule, only one carbon is bonded to four different groups are -H,-CH2Br,-CH2NH2,-Cl. Thus, the molecule has one chiral center. The priority will be given according to the Cahn-Ingold-Prelog rule, which states that the priority first is given to the molecule which has a higher atomic number. So, the priority order is:
The lowest priority is -H.
